'Brother' in the Bible

But why do you judge your brother? Or also, why do you despise your brother? For we will all stand before the judgment seat of God.

Therefore, let us no longer pass judgment on one another, but rather decide this: not to place a cause for stumbling or a temptation before a brother.

For if because of food, your brother is grieved, you are no longer living according to love. Do not destroy by your food that person for whom Christ died.

[It is] good not to eat meat or to drink wine or [to do anything] by which your brother stumbles or is offended or is weakened.

Gaius, my host and [the host] of the whole church, greets you. Erastus the city treasurer greets you, and Quartus the brother.
